Cedric J. Powell, Donald R. Baer, Kateryna Artyushkova, Christopher R. Brundle, James E. Castle, Mark Engelhard, Karen Gaskell, John Grant, Richard Haasch, Matthew Linford, Peter Sherwood, Vincent Smentkowski, Alexander Shard
Over the past three decades, the use of x-ray photoelectron spectroscopy (XPS) in research and applications has grown to make XPS the most popular method of surface analysis. There has also been an increase in the number of new or inexperienced users along

Certification of Standard Reference Material 3389 Ginsenoside Calibration Solution

May 10, 2019
Author(s)
Walter B. Wilson, Lane C. Sander, Benjamin J. Place, James H. Yen
Standard Reference Material (SRM) 3389 is intended as a calibration solution for use for the determination of ginsenosides in natural matrix samples. A unit of SRM 3389 consists of two different ampule solutions: (1) four ampules of a six-component mixture
